The southwest monsoon deficit on Friday rose to 15 percent of the benchmark long period average (LPA) from 14 percent reported a week ago.
However, the India Meteorological Department (IMD) has predicted heavy rainfall across Andhra Pradesh, Odisha and Northeastern states in the next couple of days which is expected to bring down the overall deficit in rainfall so far.
Besides, private weather forecaster Skymet has predicted a cyclonic circulation developing over North Arabian Sea off Gujarat and Maharashtra coast due to which scattered light to moderate rain is expected over Gujarat region during the next 2 to 3 days.
The IMD last month retained its earlier forecast of a deficient monsoon season (June-September) for 2015, with rainfall at 88 percent of the LPA, the same as last year. LPA is calculated on the basis of annual rainfall recorded in 1951-2000 (89 cm).
